This is a vest made entirely of knotted chain mail. All the knots are 3x4 Turk's Head knots, tied in pure silver 18ga wire.

Here's another picture of the vest, a little longer, and worn by a friend of mine.

At this point the weight is 5.1 lbs, and there are approximately 2440 knots.

I'm working on sleeves for the vest, here's is the pattern's beginning. Same knots, but I'm saving a quarter of the work by leaving four out of every sixteen knot square. Weight is about 5.73 lbs, with 2,743 knots. Scroll down for more.
